EARL G. WATBOUS, OF CHICAGO, ILLINOIS.

LAVATOBY.

Specication of Letters Patent.

Patented Mar. 8, 1910.

Application led October 2,' 1905. Serial No. `280,981.

To all 'it may concern:

Be itknown that I, EARL G. IVATROUS, a citizen of the United States, residing at Chicago, Cook county, Illinois, have invented certain new and useful Improvements in Lavatories, of which the following is a specifcaton.

My invention relates to lavatories and the like and the object thereof is to provide a simple, eicient and reliable construction of Xture, more -particularly designed for basins, having hot and cold water connections which are governed by valves controlled by a single operating handle.

The features of advanta e of my novel construction of xture wi rbe apparent from the description hereinafter given.

In the drawings Figure 1 is a sectional elevation ofmy improvedxture; Fi 2 a cross section on line 2 2 of Fig. 1; Fig. 3 a sectional elevation on line 3"-3 of Fig.y 2; and Fig. 4 a plan viewfof the fixture.

The iixture comprises essentially a casing connected to the hot and cold water supply' and containing the valves which are operated by a handle common to both valves. As herein shown, the valve casing 1 is cylindrical and positioned horizontal] With its ends closed by screw plugs 2. he casing has on either side of its middle a dependin nozzle 3 connected with the hot and col water connections l and 5 and communicating with the interior of the valve casing (when permitted by the valves therein) through the inlet ports 6 and 7 respectively, which ports are preferably in the form of slots as indicated in Fig. 2.

The valve casing is divided by the two vertical partitions 8 into three chambers, the end. ones 9 being admission chambers communicating with the hot and'cold water re, spectively, and the other or intermediate one 10, being an. outlet chamber communicating with an outlet pipe or connection 11 leading from such valve casing to the bowl or basin, or other place. Within each chamber 9 is located similar valve mechanism comprising a cu -shaped piston 12 contain- L 13 andfarranged to travel` in the chamber and over the inlet port in the manner of a slide valve. The inner end 12' of each piston is reduced in diameter with the result that when the piston travels outwardlys'niciently to uncover its inlet port the wateradmitted therethrough will be retarded while such reduced portion of the piston is intermediate the inlet port and will ,bedeflected inwardly toward the outlet chamber. By thus providing the piston with the reduced portion 12a there is formed between such portion and the inner wall of the casing or valve chamber a restricted annular space for the passage of the water from such chamber and throu h the outlet, with the result that dirt, cin ers and other foreign matter are prevented from passing beyond the inlet ports and from entering the valve chamber and prevented from eventuall becoming va ve 13 which would interfere with the proper seating ofthe saine. This construction is of advantage in this type of basin fixture inasmuch asy it is -more particularly designed for use in sleeping cars, where the supply of water is liable to contain cinders and other orei substances which would be liable to intertgerile with the proper seating embedded in the rubber ball ofthe valves, especially the rubber valves v referred to. This restricted space or passage for the water permits the water to properly flow but holds back the cinders and the like in the supply pipe and prevents them from lenterin the valve chamber.

The `uller balls are adapted to control the ports 14 through the artitions 8 and to thereby govern the supp y of water to the outlet chamber 10Q Each ball is secured to the piston or valve body in suitable manner as by means of the pin 15 passin therethrough and screw-threaded into t e outwardly projecting piston stem lwhich is guided in the screw plu- 2. Each ball or valve is normally seatedbby a coiled spring 17 within chamber 9. The pins 15 are eX- tended inwardly to constitute valve actuatgv heads or stems 18 which pass through the ports 14' and into the outlet chamber 10 and approach each other. v

r As hereinbefore stated, the valves are designed to be operated by a common operating handle whose movement in one direction opens one valve and in the other direction opens the other valve. To this end the operating stem 19 having a' handle 20 at .its upper end is provided at the lower end with a. laterally projecting lug 21 which is positioned between the valve operating stems 18 to operate either one or the other thereof accordingly as the o erating' stem and handle are turned int eV one direction or the other.

' The operating stem 19 and associated parts are constructed and arranged in the following novel manner. The operating stem bears in a hollow bearing support 22 and extends' centrally therethrough. This support or casing 22 has a flange 23 intermediate its length adapted to rest upon or against the 'bowl or basin 24 and to be clamped thereto through the medium ofl the clamping nut 25 screwing onto the upwardly projecting nozzle or connection 26 extending from the valve casing 1. This nozzle 26 screws into the lower end of the support or casing 22, with the result that the parts `described are all connected together and clamped to the casing. The stem 19 is packed by the packing 27 held in place and expanded by the packing nut 28.

Heretofore much diiticulty has been experienced in devices of the general character in question, in suitably and efficiently connecting the handle and stem and to overcome the difficulty and provide a structure which is at once simple as well as efficient, I have constructed and arranged the parts as shown in Fig. 3.v As indicated, the handle 20 is screw-threaded at its inner end so as to screw into the head 29 which has a socket 29a to receive the upper end of the operating stem 19 and bears against the upper end of the casing 22. The inner end of the handle has a centralbore in which is inserted a in 30 whoseinner end, projecting beyond such end vof the handle, is

conical and arranged to 'lit into a corre,

sponding hole or recess in one side of the operating stem or rod when the handle'is screwed in place.

It will be understood that when the handle is turned in one direction, say to the left (Fig. 1) the lefthand valve or ball is operated and its piston slid against the spring tension to uncover the inlet port 6 through which the water iiows from the supply connection 4C, and into the chamber 10, thence to the outlet 11 tothe bowl or other place of use. The liow is retarded and. deflected by the inner reduced end 12a vof the piston when the valve is first opened but after the piston clears the port the flow is full and unimpeded. When the handle is released, the spring returns vthe piston and ball, the flow being cut off gradually by means of said reduced end of the piston..

The right hand valve is operated in similar manner by turning the handle to the right. The flange 23 may be provided with the proper marks z Hot and Cold to indiJ cate which way tovturn the handle to secure either hot or cold water.

The described \construction provides a fixture which is not only reliable and etlicient in operation, but also durable and capable of being readily put in place and assembled.

I claim:

1 A basin fixture for hot and cold water comprising a valve casing having ports connecting respectively with hot and cold Water supplies and having an outlet, valve mechanism governing at two points the flow of water from each port to the outlet and arranged to deflect the flow at one of said points and to cause the water to pass through a restricted space, and means for operating the valve mechanism; substantially as described.

2. A basin fixture comprising a valve cas- `ing 4having a chamber communicating with the water connection or inlet and having an outlet and a valve operating in said chamber for controlling said inlet and outlet and consisting of a piston having a portion adapted to seat on the inlet to close the same and arranged to travel in said chamber,

saidpiston having a reduced portion 12a whereby a restricted passage is provided for the flow of water between the piston and the inner wall of the chamber to thereby prevent the passage of foreign substances beyond the inlet port; substantially as dei scribed.

3. A basin fixture for hot and .cold water comprising a valve casing having two partitions dividing the same into the two end lnlet chambers and middle outlet chamber v110 and provided with ports 14, each of said lend chambers having a port arranged to communicate with a source of water supply,

valve mechanism in each chamber for gov erning its ports, each valve mechanism comprising a hollow piston 12 movable in its chamber 9 to govern its water supply port and a-Fuller ball arranged within said pis ton to govern its port 14, said piston having a reduced portion 12a to provide a restricted space for the flow of water, a stem or head 18 projecting from the ball inwardly through port 14 and into outlet chamber l0, and means'for actuating said head and thereby operating the valve;y substantially as described.
